const(BigInt) to BigInt
const(BigInt)/const(BigInt) do not compile.

Is it a bug or design considerations?

test.d

import std.stdio;
import std.bigint;

void foo(BigInt b)
{
	std.stdio.writefln("foo(%s)", b);
}

void main()
{
	const BigInt b = BigInt("445216415446");

	auto b1 = b / b;

	foo(b);
}

$ dmd test.d

It was a const correctness bug, but it's already fixed in recent 
D compilers.

It will be fixed in dmd 2.065. It's not yet out but you can use 
it already if you want to be on the "bleeding edge", it's 
currently in beta3 and most regressions are fixed, so it's 
probably better than using dmd 2.064.2.
